Forwarding emails in Exchange 2013/2016. How to setup?

Question

Microsoft Exchange

Implemented exchange 2016, everything is fine. Except for one crap. Email forwarding doesn't work.
This is not a forwarding to another mailbox, but a redirection with the original sender's address
. The user selects "redirect" in the Bat's pop-box.
Writes
5.7.60 SMTP; Client does not have permissions to send as this sender
Or is this not possible at all on exchange?
google is silent

Answer 1

Hello
Most likely, you need to give the right to send on behalf of the desired user

Answer 2

I tried different stuff there.
But letters come from heaps of external addresses.

Answer 3

You need to enable anonymous sending for internal IP addresses - it's better to create a separate receive connector.
